Wonderful experience - Wonderful experience and good timing. It touches all major areas of Vienna and neighbourhood. Saves you lots of walking

Great way to explore..... - For ease of sightseeing around the city this couldn't be better. We completed the 3 tours over 2 days giving ample opportunity to visit places of interest . The commentary was excellent, the buses ran on time ,and the boarding staff most helpful.

Great experience - This bus line was definitely much better with the narrative and bus cleaness. The wait was average and staff pleasant.

I believe the best way to... - I believe the best way to explore the city it's by taking the Hop on first and second part by walking to .c

Fine, but could be better - Excellent tours, but the Dutch version of the tour was not very good. Friendly staff, clean bus.

Needs Improvement - The location of where to redeem your tickets is not clear and the kiosk where they redeem it took 20 minutes to process (while I apologized to others in line) bc their machine couldn’t read the bar code. Embarrassing for them and for my family. There shouldn’t even be a need for the ticket redemption process, just issue digital tickets!

Worthwhile - This was a good investment. However….wifi on the bus was advertised and did not work. We were counting on this. Also, several of the headphone ports were not working either. Luckily the bus wasn’t full and we could switch seats until we found a working port. Overall, worthwhile in order to see the sights.

Ignorant Drivers/Workers - The Yellow Line bus which left the Opera at 2:30 or 2:40 PM DID NOT STOP at the Hauptbanhof. The driver drove right past two buses that were already there and kept going. When I ran downstairs there were two workers besides the driver. I asked why they didn’t stop and he said “We didn’t know anyone wanted off.” I said “How could you know that unless you stop? We wanted off.” Then he said “Well, you can get off at the next stop and walk back.” which would have been over a mile. I finally had to make them open the doors at a stoplight, which he didn’t really want to do and we had to walk half a mile back to the Hauptbanhof. You should fire all three of those guys.

Very scarce - I would say expensive and the service terrible!! The bus runs every hour. I would say that waiting outside for an hour for a bus is really excessive

Hopeless - try a different operator if you want to actually see Vienna! - Terrible service ….. we naively bought a 48 hour pass thinking that this was a better set up / routes than other tours. We were very wrong sadly. - Buses in January are roughly every hour at stops so it really matters when you miss one. Our first attempt saw us at the right bus stop (marked and numbered) where we watched the bus drive straight past after waiting 10 mins past the due time. If you are expected to request this should be very clear. It’s not. - We then finally made it on a bus at Schloss Belvedere to be told by the bus driver we’d have to get off at the next stop (the Opera House appears to be a terminal). He said we’d need to get on the next bus - not that that bus was an hour wait! In the cold…. - Eventually got on a bus an hour later and had a successful round on the Red Line - Next day we walked to Praterstern Station and thought we’d pick up the Blue Line bus at the stop there. The description of the stop was hopelessly generic (by the UBahn Ausgang and Prater exit - at a big station with a number of places fitting that description). After 25 mins, missing yet another bus we rang the phone number and were (helpfully to be fair) directed to the right stop. Outside a very Googleable restaurant which could easily have been the description. - By this time we didn’t have the time to get round the loop and therefore gave up on our plans to see a few sights Overall a tourist service that hasn’t been designed with tourists in mind - at all.
